Does it produce a hum over the speakers when there is no input? I have a SANOXY one that I bough that does that and it is very annoying.

I've had mine for a while now and use it everyday, no humming at all, solid product.

I've never heard any buzz when I have if off, even though it is connected to a receiver. Before though it didn't make a sound and works fine.

I use it specifically to send TV audio to my sound bar. I haven't detected a hum. However, I normally unplug it when I'm not using it.

Probably a connection issue with one of the components hooked to the TV (mine happened to be a Sony DVD player...) removed that and the hum went away. Gave me an excuse to get a progressive scan DVD player... hooked it up and still no noise. It took me a bit to narrow it down, since I've got so many console systems. ;)

Ours makes a small cyclic hum. You can hear it. It doesn't bother me, but everyone has different tolerances.

There is a low humming when it kicks on but if you aren't standing right next to it you wouldn't hear it. I have noticed that if I need to clean the shield part it seems a little louder, but all it needs is a good wipe down and it's back to the way it always is.

There is a very very quiet hum. I cannot hear it unless my put the timer to my ear.

I never noticed it. I kept an iPad, iPhone, multiple halogen-dimmed lights on within two feet of the unit . . then tried them all off, when I was having the static/hum issue. The static only came from the remote: I'm convinced of that. If you keep the system on when NOT using the audio input, you can detect a very low-level, hum from the Cyber Acoustics system being on and, I assume, "waiting." But it's NOT the static and loud hum I was hearing, when I requested a replacement remote pod. That sound was incredibly loud, harsh, and distracting. This circuit hum is almost undetectable but is present, if you're a hyper sensitive type. My AC kicks in (which is quiet) and completely camouflages this circuit hum, as the sound is so faint. There you go....

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too. Maria

I noticed it too. When the device is connected via the instrument connection the floating ground will cancel any noise. One must remember, this isn't a professional piece of equipment with layers and layers of MOSFETS, JFETS AND TRANSISTORS To switch on and of the signal. So, even though there is no signal, it's amplifying the hum from the AC transformer as well. In common terms, it needs to be connected to a device to cancel the noise. Even in the ground, or lift phase.

Is it a ground hum? Because if the speaker has a hum, there is nothing wrong with the speaker itself.

it solved my humming problem when i used 2 or more components plugged into my receiver. but when i got a more powerful amp i didnt need it. i would try it...you can always return it.

Mine is crystal clear.. I had a low freq amplifier type "hum" in my system but that was fixed by using RG58 to carry audio to my subs.. (was picking up interference from A/C power systems in room)

Sorry to be so long, but while the problem seemed to clear up, it suddenly developed the hum again. I have a Technics receiver with a phono output, so I have the turntable set to Phone Off. This worked until today, when it suddenly developed a hum, and when I tried to reconnect the wires the white wire produced a pronounced hum and the red wire produced an explosive pop. I played it this afternoon without incident, and have played it for hundreds of hours since last summer, but today the hum came back with a vengeance.

It has a slight hum, but not noticeably loud. I've had it for about 6 months, and there's nothing I would complain about it

It has a very low hum. We have it installed in an attic above the living room and it can't be heard from there.

Haven't noticed a hum. We have 3 of them in our kitchen and, even when things are quiet and the lights are dimmed or all the way up, haven't noticed anything unusual. Wondering if you got a defective batch?

I had surround sound and two of the 7 speakers hummed when I put the Direct TV HD in "pause." To fix this problem go to the Direct TV remote, setup, settings, audio, and turn "on" dolby digital. Mine was off and caused the hum!

I'm not sure of the design details but suspect the low power setting has a smoother sine wave output so won't cause "hum" in audio when used to power audio devices. Aybe somebody else as looked into the design in detail.
